How System Size, Duct Condition, and SEER Impact Price

Size and ductwork condition are the largest variables; an extra ton adds $700-$1,500 to installed price while full duct replacement adds $2,000-$6,000.

Numeric thresholds: upsize from 3-ton to 4-ton typically raises unit cost by $800-$1,400 and labor 10-30%. Major ductwork (full replacement) occurs often when home >2,500 sq ft or ducts are >20 years old.

SEER effect: moving from 16 SEER to Carrier 18 SEER generally increases unit price by $300-$900 but can lower annual cooling costs by $60-$200 depending on local cooling load.
